piclc up allloose -grain without" the end thereof r-unningintotheground.v

A. further object of my inventicrr is to. pro. vide a device of thecharacter herewithin described which is of eminentl simple construction,economical to manufacture and which will give long service forthe-treason- .that. breakages will be most infrequent since the devicedoes not tend to run into the ground as does the conventional pickup'assembly;

With the above more important objects in view andlsuchlother minorobjects as: may appear as the specification proceeds, myinventionrconsists essentially in th arrangementand construction of:par-ts all as hereinafter more: particularly: described; reference beingharltmthe accompanying drawings in which- Figure 1 is a side elevationof a pick-up assembly embodying my novel; modificationsthere tin Figure2 is an exploded perspective View of the parts 5 and 8 intended toillustrate the interior structure thereof.

My pick-up assembl comprises the conventional forwardly projectingbracket l which is bolted or strapped to the underside of the usualcutter-bar guards 2 at the points 3 and 4.

The forward end of the bracket I terminates in the stationary part 5 ofthe conventional two-part hub 6.

My pick-up element 7 comprises collectively the rotatable portion 6 ofthe hub S which is bolted to the portion 5 at the centre thereof bymeans of a conventional square headed bolt 9; the forwardly anddownwardly curving runner l0 which projects forwardly from the rotatableportion 8; the upwardl and rearwardly diverging carrying arm i i whichjoins the runner at the forward end I2 thereof; and the carrying armitself.

The portions 5 and 8 of the hub 63 are hollow on the inside therebyproviding a semi-circular housing portion 43 for a cushioning spring M.This cushioning spring is positioned between the abutments i5 and 26,the former of which is integral with the stationary part 5 of the hubwhile the latter is integral with the rotating part 8. From theforegoing it will clearly be recognized that upon rotation of thepick-up element in a counterclockwise direction, as for in- 5,5

stance when: a, rocle or; hiilockt, encountered, thezupner end of;thee-spring will ultimately: come into contact: withxthe abutment i5 topltovid'eza cushioning: efi'eota. In; this; contextiit; is howeverta-banoted: that. the spring.- i-ihis not. intended tot-extend fOIr the;fulltlengthi or the. scrub-circular housing portion 1| 3; but hunctiona.as: already stated -only as a-..cnshionror:buffer: From this it will beunderstood that the,element1-is-;free to pick-up, .freely-toriaroertainiextent without the, intervention of; anyyresistance by; the spring;

Upon. the. left. hand side of the; hub-portion 8rwith respecttoaliiguneallis a semi-circularrslot I;L. through which asnutl-andstop.-bolt-. assembly LBf-PltOjdGliSi ,itr being: understood: that the:nut of thesassembly 18; may bezboltedi at. arm-point. upon tha-lengtmof:the slot-I51, being intended-to come uplagainstl the, abutment id-and.which: projects from. and is integral. with. the. hubrportion; 5.

In this way, the position of theepickl-upelement 1 may be adjustedalthough. his; topbe understood .thatl in the; adaptation. of. the.foregoing structure; to, purpose. I do i not make use of such.ad-iustmenh. and furthermore, make use. of, a. shortenanch weaker springthan. is, commonly used in association with pick-up attachments. As hasbeen clearl indicated in the accompanying Figure 1, I permit the runnerand carrying arm l0 and H to drop clockwise so that the forward end l2thereof is as low as possible. Thus it will occupy a position in a planewhich is wholly below the lowermost peripheral limit of the hub, or inother words, as low as is permitted by the stop 20 which projectsinwardly from the rotating part 8 and moves in the recess 2| in thestationary part 5 until it comes up against either of the shoulders 22at the ends thereof.

All the foregoing represents conventional structure in relation topick-up assemblies for attachment to cutter-bar guards with theexception of the fact that my spring I4 is shorter than those commonlyused, which latter occupy, while in varying degrees of tension, the fulllength of the housing portion i3. In conventional practice however it isto be understood that it is only very rarely that it is at allpracticable to permit such an adjustment of the hub 6 that the forwardend l2 may drop down as far as is permitted, because under suchcircumstances the point or end l2 repeatedly digs into the groundcausing frequent stoppage, breakages and sometimes serious damage.

It is however desirable for maximum downgrain recovery that the pick-upelement 1 be vesting conditions to slacken the nut and bolt' assembly l8such that the pick-up element as-awhole may drop to its limit asillustrated.

Only when the forward end of the pick-up element is in its lowermostposition is it possible to pick-up the maximum amount of loosev grain,

but without the extension finger 23, this is not practicable for whichreason the forward end 12 must be raised by adjustment of the nut andbolt assembly I8 in the slot l1. But obviously this permits the escapefrom underneath the pick-up element of a considerable quantity of loosegrain. However, by the use of the extension finger 23 which I have nowdescribed, the maximum amount of loose grain is collected while avoidingthe tendency of the element to dig into the ground.

Since various modifications can be made in I my invention as hereinabovedescribed and many apparently widely diiferent embodiments of same madewithin the scope of the claims without departing from-such spirit andscope, it is intended that all matter contained in the accompanyingspecification shall be interpreted as illustrative only and not in alimiting sense and I desire only such limitations placed thereon as arespecifically expressed in the accompanying claim.

What I claim as my invention is:

A pick-up assembly for attachment to cuttingbar guards, comprising incombination a forwardly projecting bracket secured to said guard, acircular two-part hub, one part of which is 4 stationary and integralwith one end of said bracket, a pick-up element, the other end of saidhub being rotatable and integral with said pick-up element, means forholding said twopart hub rotatably together, a runner curving forwardlyand downwardly from said hub, said runner constituting part of saidpick-up element and being integral with and projecting forwardly fromthe rotatable part of said hub, a carrying arm diverging rearwardly andupwardly from the forward end of said runner, an upwardly curveddeformable extension finger projecting forward from the junction of saidrunner and said carrying arm, a semicircular housing portion between thetwo parts of said hub, opposing abutments terminating said housing, oneof said abutments being integral with the stationary part of said huband the other integral with the rotatable part, a cushioning springwithin said housing of a length less than that of said housing, therotatable part of said hub being freely movable without resistancethereagainst by said spring when said runner attached thereto is inground contacting position, the junction of said runner and saidcarrying arm lying in a plane below the lowermost peripheral limit ofsaid hub when in situ and when the associated cutter-bar is lying in orbelow a horizontal plane.
